I installed the latest kernel version (3.0.0-15) through the Muon package manager of Kubuntu 11.10 but when I reboot the system it doesn't appear on grub list so I can use only the 3.0.0-12 kernel version. Synaptic reports that it's installed the kernel 3.0.0-14 version too but it doesn't appear too. The 3.0.0-14 and 3.0.0-15 versions didn't have the kernel image installed so I tried to install them but they don't appear on grub list in any case. Any idea? Many thanks in advance!

You have to update the grub list. I am not sure whether sudo update-grub is all you need. – Martin Ueding Dec 15 '11 at 15:04
Please post your /boot/grub/grub.cfg and the output of ls /boot/ – Jordan Uggla Apr 4 '12 at 7:14

Try to:

sudo update-initramfs -u


sudo update-grub

Earlier with the Kubuntu:

The package manager should do this by default. Looking old logs:

Log of sudo apt-get dist-upgrade Sat Dec 10 21:43:55 2011

The following NEW packages will be installed:

Setting up linux-image-3.0.0-14-generic (3.0.0-14.23) ... Running depmod. update-initramfs: deferring update (hook will be called later)

run-parts: executing /etc/kernel/postinst.d/zz-update-grub 3.0.0-14-generic /boot/vmlinuz-3.0.0-14-generic Generating grub.cfg ...

man update-initramfs:
